Question

I am working on some image processing tasks.

I have made low resolution Bitmap using getDrawingCache() and createScalledBitmap()

But when I resize this image to high resolution say 612 X 612 my image is getting blurred. And it looks so bad.

Is there any way to resize images to high resolutions without losing pixels ? Does openCV has this kind of classes ?

I have solved this using Assets..

(1) Put my all images in asset folder

(2) Read images using inputstream

now i dont need to resize it and it works fine as i want. like this:

private void setThemeBackgroundImage(String imageName, Button themeButton) {

        try {
            InputStream backgroundBitmap = getAssets().open(imageName);
            Bitmap immutableBitmap = BitmapFactory
                    .decodeStream(backgroundBitmap);

            themeButton.setBackgroundDrawable(new BitmapDrawable(
                    getResources(), immutableBitmap));
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }
